SLED-BENCH.

Application filed April 26, 1915.

To all whom, it may concern:

Be it known that I, Or'ro PEARSON, a subject of the King of Sweden,residing at Mount J ewett, in the county of McKean and State ofPennsylvania, have invented certain new and useful Improvements in Sled-Benches; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in sleds of the type havingflexible runners and more particularly to benches for sleds of thischaracter.

The primary object of the invention is to provide a simply constructedand eiiicient sled bench which while strong and durable is cheap tomanufacture.

Another ob 'ect is to provide a sled bench so constructed that when theparts are assembled they will hang together without the use of rivets orother connecting elements.

IVith these and other objects in View, the invention consists of certainnovel features of construction, and the combination and arrangement ofparts as will be more fully described and claimed.

In the accompanying drawings: Figure 1 represents a side view of a sledequipped with this improved bench; Fig. 2 is a bottom plan view thereofFig. 3 is a vertical transverse section taken on the line 3-3 of Fig. 1;Fig. i is a longitudinal section taken on the line l4: of Fig. 3; Fig. 5is a detail perspective View of the bench; Fig. 6 is a detailperspective view of one of the knees; Fig. 7 is a similar view of thecross bar of the bench, and Fig. 8 is a plan view of the blank fromwhich the knee is constructed. Fig. 9 is a detail perspective view ofone of the knees detached.

In the embodiment illustrated, a sled S is shown having the usualrunners R which may be constructed of any suitable material with anydesired cross sectional contour. A top T is shown supported by therunners R and connected therewith by benches 1 which constitute thisinvention. A steering bar A is shown connecting the top T with the crossbar B which connects the front ends of the runners to adapt them to beflexed for steering purposes, but this construction is not necessary forsleds equipped with this invention, as these benches may be employedwith any form of sled.

Specification of Letters Patent.

Patented May is, mic.

Serial No. 23,942.

The bench 1 which constitutes this invention comprises a cross bar 2 andknees 3 and 4.- which are connected with the opposite ends of the crossbar in a manner to be described.

The cross bar 2 is'preferably constructed from a single piece of sheetmetal which is bent to form a channel bar as shown in Fig. 7. The endsof this cross bar 2 are offset downwardly from the top of the beam toform seats for the side bars of the sled frame, said offset ends beingapertured to receive fastening elements for securing them to the sidebars. This cross bar 2 is also provided in the side flanges 5 thereofwith longitudinally extending registering slots 6 which are arrangednear opposite ends of the cross bar inside the offset portion thereofand which are designed to receive the knees to be described.

The knees 3 and 4 which support the ends of the cross bar or beam 2 ofthe bench are connected with the runners R and are preferablyconstructed from the blank shown in Fig. 8 to adapt them to be made fromsmall sheets of metal, thereby economizing in the construction of saidknees. The blank from which each knee is constructed comprises a bodyportion 7 or connecting plate having diverging arms 8 which arepreferably bifurcated at their free ends to form attaching lugs forsecuring the knees to the runners, but not necessarily so, as theseknees may be secured to the runners in any suitable or desirable manner.The body portion 7 of the blank from which the knee is con structed isleft unfolded and is preferably of a width corresponding to the lengthof theslots 6 through which it is adapted to be passed, and extendstransversely across the bar 2 with the ends thereof bent downwardlywhere they merge into the arms 8 and which closely hug the side flanges5 of said cross bar. This body portion 7 between the arms 8 of the kneemay be provided and is here shown so provided with apertures 9 toreceive connecting rivets for securing the plates to the sled body, saidrivets also passing through the body portions of the knees andconnecting the knees to the cross bar.

The body portion or connecting cross bars 7 of the front knees 3 and 4have their inner edges made longer than their outer edges as shown at 10and which are provided with transversely extending arcuate slots 11 toprovide for the movement of the knee relatively to the bench on theflexing of the front portion of the runners R. It is of courseunderstood that one of the rivets passes through these areuate slots 11,said slots being provided to permit the knee to move relatively to therivet, the other rivet which extends through the outer edge of the bar 7forming a pivot for the knee together with the slotted connection of theknee with the cross bar. From the above description it will be obviousthat this peculiar connection of the knees with the cross bar of thebench will cause said members to reliably hang together without the useof any rivets or other connecting elements, but rivets are here shown toform auxiliary fastening members although they need not necessarily beemployed for connecting the parts of the bench, but being necessaryforconnecting the sled body to the bench, they are preferably continuedon through the bench members to assist in holding them together. Whilethis cross bar 2 is shown and described in the form of an angle bar, itis obvious that it need not be necessarily so formed, as any other barmight be employed and slotted transversely to receive the knees andoperate in the same manner, the construction shown being preferablehowever.

By constructing the cross bar and knees as shown and described, they maybe cut from strips of metal with practically no waste except for theholes and slots and yet when assembled form a very strong, light anddurable bench, and the connecting plates of the knees which extendtransversely of the channelshaped bench cross bars operate asreinforcing members to prevent the cross bar from buckling.

The knees 3 and 4: when applied should be spread about five inches aparton the runners, more or less, and the knees should slant so that theirends will come directly under the holes at the ends of the channel.

The part of the knee which passes through slots in channel member may beof any suitable shape or size to fit properly into said slots. Certainreinforcing elements similar to those in my co-pending applicationSerial No. 11234, filed March l, 1915, may also be used if desired.

I claim as my invention:

1. A sled bench comprising a unitary cross bar having slots extendingtransversely therethrough, and pairs of knees, each pair having aconnecting plate extending through one of said slots.

2. A sled bench comprising a channel bar having oppositely disposedregistering apertures in the side flanges thereof, and knees having aconnecting plate extending through said registering apertures.

3. A sled bench comprising a channel bar having oppositely dlsposedreglstermg apertures 1n the side flanges thereof, and knees having aconnecting plate extending through said reglsterlng apertures, with theupper ends of the knees engaging said side flanges,

the connecting plate of said knees corresponding in width to the lengthof the apertures in the flanges of the bench cross bar and the length ofthe connecting plate of the knees at one edge corresponding to the widthof the bench cross bar.

if. A sled bench comprising a channel bar having oppositely disposedregistering apertures in the side flanges thereof, and knees having aconnecting plate extending through said registering apertures with theupper ends of the knees engaging said side flanges, the connecting plateof said knees corresponding in width to the length of the apertures inthe flanges of the bench cross bar and the length of the connectingplate of the knees corresponding to the width of the bench cross bar,the connecting plates of the .front knees having their inner edgeslonger than their outer edges to provide for the pivotal movement ofsaid knees relatively to the cross bar of the bench.

5. A sled bench comprising a channel bar having oppositely disposedregistering apertures in the side flanges thereof, and knees having aconnecting plate extending through said registering apertures with theupper ends of the knees engaging said side flanges, the connecting plateof said knees corresponding in width to the length of the apertures inthe flanges of the bench cross bar and the length of the connectingplates of the knees corresponding to the width of the bench cross bar,the plates of the front knees having their inner edges longer than theirouter edges to provide for the pivotal movement of said knees relativelyto the cross bar of the bench, said longer plate edges being providedwith transversely extending arouate slots, and apertures in the crossbar of the bench for the passage of fastening rivets through said benchand knee plate.

6. A sled bench comprising a cross bar having slots extendingtransversely therethrough, and knees having connecting plates extendingthrough said slots, the inner edge of each plate being longer than theouter edge thereof.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
